Help with saz3000d humming

[Jared Harper 0]

Ok, so I just received and hooked up my saz3000d and everything went smooth. It is a very powerful amp. However, I am having one issue. While the truck is NOT running and my head unit is paused, or the av source is off (it is a avic-n4 nav) so the hu itself is still on, and so is the amp. There is a low humming sound coming from my subs. Something else I notice is when I touch the amp it either goes completely away or almost does. Can anyone shed any light on this for me please.

More info you may want:

I have quality rca jacks no where close to any other wires.

I relocated my ground with no change.

I have a memphis eq.

Oh and also, the hum last for about 10 seconds every time. Then is stops completely for about 5 seconds, and the loop continues.

I think it's the ground......... sounds like it.

well, yes and no. I am in the seat but only touching fabric, no metal.

It's some kind of static energy. You're discharging it by touching the metal.

Have you completed the big 3 under the hood and made sure the under hood grounds are attached to clean, bare metal?

I have done the big three with 0 gauge. Scraped away all paint on every ground connection. My ends are soldered.

rereading this. your headunit is on, its paused. is it auxilary or a cd or radio playin(before it was paused). it might be the aux cord if your using that when the noise is there. if not that, then maybe the rcas. i had some broken rcas once and tryed to strip and reconnect them. that added a humming noise

so maybe redoing the ground on the headunit or even grounding the rcas

maybe i should wipe my interior down with a bounce sheet!

The rcas are fairly new, but I think that they may be the problem. I will try it tomorrow. When paused it is running aux but it does it even when the av source is off without the aux being connected.

Ok guys I have the problem solved. I want to thank everyone for their help. To my surprise the problem was the RCAs which was strange to me because they were new and expensive with a huge jacket meant to keep interference out. Grounding them didn't help. But I put in some different ones and the noise is gone.

I get by fine with my 3 dollar parts express rcas, high dollar rcas are overrated.

I know you said you found the issue.. but thought I'd add..

***this may not be fact but is what I understand

it's normal.. All the saz's humm at idle--I was concerened about mine as well. I didn't talk to jake on it but the other competitors said theirs did the same thing... -the amp itself-- it's not normal if it's coming through the woofers. they gave a good reason for it but I don't recall what that reason was
